... were performed, showing an evident EOR effect compared with sea water, in increasing the oil recovery up to 7%. Simulation work to predict the benefits in the field was executed. Core experiments were reproduced using a wettability change model to obtain low salinity water parameters, the salt...

.... In fact, these factors can favourably impact, in a synergic way, some critical parameters associated to oil recovery such as oil/water interfacial tension, wettability and oil viscosity. Surfactant adsorption/retention as well as rock/nanoemulsion interactions have been also evaluated. The future...

Even though the mechanism of residual oil mobilization is still not well known, the coexistence, in nanoemulsions, of small droplets size, surfactants mixture and solvent could favorably impact on critical parameters such as oil/water interfacial tension...

... mechanisms behind the extra oil recovery obtained by such process. Synthetic formation brine at 20% salinity and Saudi medium crude oil were used as formation fluids. Sea water collected from the Arabian Gulf and different diluted versions of sea water were used as displacing fluids in tertiary and secondary...

The experimental data were reproduced to derive input simulation parameters to describe the chemical EOR process: the benefits...

... Abstract A vessel of opportunity for riserless light well intervention (RLWI) can lead to accelerated oil recovery. Since a rig was not an economical solution and a slot on a purpose built intervention vessel was unavailable (9 mo. away), a vessel of opportunity was utilized for riserless...

The final oil recovery was higher in the cycles where the sequence was initiated by water injection before the immiscible gas. Numerical simulations of the experiments were performed and microscopic sweep efficiency...
